Aquatherm Omega wood boiler

RoosterBoy

hr

a prototype

that I saw a month or so ago. Built a stones throw from Wirsbo as many here will reconize th location:)

The fab shop that is manufacturing this boiler has some great tools for steel working.

I'd like to see Team Aquatherm and the Omega at the Wetstock!

Any chance Dave, Bill, or Bob?

Omega at Wetstock

The chances of us showing one at Wetstock are great if it's ok with Dan. Dan?

About the Aqua-Therm Omega

Thanks for the mention Hotrod. Yes, Aqua-Therm does have a new "stove" available.

We had looked at all the current technologies that are used in all wood stoves and see the same thing with all. You can claim certain effiencies but based on what? All the stoves out there, our Aqua-Therm model included, work on some basic principles. Load with wood, whatever size, light the fire and let it burn. As it burns, it heats the water jacket that surrounds the firebox. It's the way we all do it. The problem with that is that it NEVER allows for all 3 stages of combustion, based on the laws of physics.

The three laws are fairly simple. Wood starts to burn, boiling out the moisture (212 degrees), wood starts to change it's chemistry (500 - 600 degrees) and starts to put out volatile gases as it breaks down. Those gases contain between 50-70% of the available energy from the wood. Typically at this point, we all (manufacturers) allow those gases to escape out the stack.

Some will claim that they increase "burn time" but to reach stage 3, it requires constant temperatures of >1100 degrees to ingnite the gases, changing their moleculer structure. It is virtually impossible to achieve temps of 1100 degrees when any firebox is located next to the water jacket because "quenching" takes place. How do you get the temps into that range when you surround it with 180 degree water? Does not work. Can not work (unless you know how to change the laws of physics).

Aqua-Therm has just introduced a new stove that works on the gasification principles. Firebox holds the wood, draft is induced and drives the gases through the coal bed (which see temps in the 1200-1600 degree range) creating superheated exhaust that has taken most of the available energy from the fuel source, in this case the wood, and drives the gases throgh a seperate chamber to heat the water. The key here is that the firebox and the water jacket never see each other, and, the gases are ignited on a consistent basis. All 3 stages of combustion take place. The stove, and by the way, we're now calling it an appliance, is U.L. tested and will soon have ASME. It is all stainless steel and manufactured in one of the most state of the art facilities in the Twin Cities, laser cut, robotics, etc. Each unit is produced to a tollerance of 1/1000th of an inch.

Sorry to ramble, but am very excited with our new product that has been in development for quite some time. This industry is ready to be dragged into the 21st century.

Thanks for the forum,

New Aqua-Therm Omega

Back in May we heard about Aqua-Therm's new Omega stove and was wondering if anyone has heard back from Dave and his gang from Minn.?

Last week an operator/homeowner was drilling me..

for some how 2's on piping arragements for his new wood boiler that uses gasification *~/:) it sounds to me like you have certainly found a market willing to invest some dollars in this century type technology :)Good Luck.p.s. we have a heck of alot of trees around here

The Aqua-Therm Omega is out

The Aqua-Therm Omega has hit the market to a very strong welcome. We're seeing strong demand for this top of the like wood burner

Hey Dave,

I remember either reading an article, or someone telling me that MIT developed something like this back in the 50's.

They ran the gasses through a refractory tunnel to get the temps up, then the burning/burnt (was never really sure about this part) was drafted through the water box.

Do you know anything of this?

Thanx!

That design

Has been in production for over 20 years. It's one of the most efficient wood burners you can get. Check out the Garn wood heater made by Dectra industries. It has a primary combustion chamber which dumps the gases into a "ceramic" chamber which will hit 1800*+, then the HX makes 5 passes through a very large btu storage tank. This unit can be sidewall vented. It is one of the very few that have actually been tested by an independent lab to establish realistic efficiency ratings.

One of the interesting features of this unit, and one that points out its efficiency, is that the combustion blower sits at the END of the heat transfer tubes. It draws the combustion gases through the HX instead of just blowing air under the fire like everything else I have seen.

It is a wood burner for people serious about burning wood.

That just

may be the one Steve!

Types of coal

may i ask what probably wasnt exactly part of the main thrust of your development teams main concernes or objectives? the question would be what grades of coal,coke, or peat moss ,wood pellets can burn efficently in the omega? Are there any guidelines on mixing say coal and seasoned birch for example..?
